We assessed changes in the body image of Spanish adolescents who participated in a programme aimed at preventing disordered eating, with a 30-month follow-up. 254 girls and 189 boys aged 12–14 were assigned to a control group (n = 201) or one of two possible experimental conditions: media literacy programme (ML, n = 143) and media literacy plus nutrition awareness programme (ML + NUT, n = 99). Body image was assessed with the Body Image Questionnaire (Qüestionari d’Imatge Corporal; QÜIC). Pre-test, post-test, 7- and 30-month follow-up measurements were taken. Linear model analyses were carried out with a 2 × 3 × 3 ANOVA (sex × group × phase), adjusted by the baseline level. At 30-month follow-up, ML and ML + NUT participants showed fewer body problems and more body satisfaction than the control group. There is a need for prevention programmes addressing eating and body image disturbances that involve both boys and girls. 相似文献

The role of implicit theories in romantic relationships was investigated in two studies. People holding a soulmate theory, who believed that finding the right person is most important for a satisfying relationship, were compared to people holding a work–it–out theory, who believed that effort is most important for building a successful relationship. In Study 1, college students (N = 527) completed a set of questionnaires, including measures of relationship theories and functioning within romantic relationships. Approximately 8 months later, a subset of these students (N = 176) completed a second set of questionnaires for Study 1. The implicit theories were highly stable over time (r = .74). For soulmate theorists, feelings that one’s specific partner is ideal predicted relationship satisfaction and relationship longevity to a greater extent than for work–it–out theorists. Whereas Study 1 investigated people’s theories of relationships as ends of a bipolar continuum, a separate study explored people’s theories of relationships as two unipolar dimensions. Findings from Study 2 (N = 266) supported a representation of the theories as two negatively correlated factors, and supported findings from Study 1 highlighting the role of the interaction between the relationship theories and partner fit in predicting relationship satisfaction. 相似文献

To analyze the impact of outline shape on visual word recognition, the visual pattern of the stimuli can be distorted by size alternation. Contrary to the predictions of models that rely on outline shape (Allen, Wallace, & Weber, 1995), the effect of size alternationwas greater for low-frequency words than for high-frequency words in a lexical decision task (Experiment 1). In Experiment 2, the effect of case type (lowercase vs. UPPERCASE) occurred for low-frequency words, but not for high-frequency words. The effect of neighborhood size was remarkably similar in the two experiments. The results can be readily explained in the framework of a resonance model (Grossberg & Stone, 1986), in which a mismatch between the original sensory pattern and the abstract orthographic code slows down the formation of a stable percept. 相似文献

We evaluated the impact of RIPP-7, a seventh grade violence prevention curriculum designed to strengthen and extend the effects of the sixth grade RIPP-6 curriculum. Classes of seventh graders at two urban middle schools serving predominantly African-American youth where RIPP-6 had been implemented the preceding school year were randomized to intervention (N = 239) and control groups (N = 237). Compared to students in the control group, students who participated in RIPP-7 had fewer disciplinary code violations for violent offenses during the following school year. A limited number of main effects were found on self-report outcome measures and measures of attitudes. Although significant main effects were not found on self-report measures of physical aggression, drug use, or anxiety, analyses of interactions with pretest scores indicated that intervention effects were significantly moderated by pretest scores for several outcome measures. Students most likely to benefit from the intervention were those who reported higher pretest rates of problem behaviors including violent behavior, nonphysical aggression, and delinquent behavior. 相似文献

In this study, we investigated the prevalence of women's sexual aggression against men and examined predictors of sexual aggression in a sample of 248 women. Respondents reported their use of aggressive strategies (physical force, exploitation of a man's incapacitated state, and verbal pressure) to make a man engage in sexual touch, sexual intercourse, or oral sex against his will. Childhood abuse, gender role orientation, ambiguous communication of sexual intentions, level of sexual activity, and peer pressure were included as predictors of sexual aggression. Almost 1 in 10 respondents (9.3%) reported having used aggressive strategies to coerce a man into sexual activities. Exploitation of the man's incapacitated state was used most frequently (5.6%), followed by verbal pressure (3.2%) and physical force (2%). An additional 5.4% reported attempted acts of sexual aggression. Sexual abuse in childhood, ambiguous communication of sexual intentions, high levels of sexual activity, and peer pressure toward sexual activity were linked to an increased likelihood of sexual aggression. The findings are discussed in relation to the literature on men's sexual aggression. 相似文献

This paper presents two uniqueness theorems for the family of hierarchical classes models, a collection of order preserving Boolean decomposition models for binary N-way N-mode data. The theorems are compared with uniqueness results for the closely related family of N-way N-mode principal component models. It is concluded that the two-way two-mode PCA and N-way N-mode TuckerN models suffer more from a lack of identifiability than their hierarchical classes analogues, whereas the uniqueness conditions for N-way N-mode PARAFAC/CANDECOMP models are less restrictive than the ones derived for their N-way N-mode hierarchical classes counterparts. 相似文献
